Artificial Ascension (Occult Realms pg. 12): You can upload your consciousness into a robot, becoming an artificial intelligence. Performing this ascension requires uninterrupted access to a construct with the robot subtype and at least 10 Hit Dice for 24 hours, during which time you cannot perform other tasks. Any interruptions cause the upload to fail. At the end of the 24 hours your consciousness is successfully uploaded into the robot. If the robot is not willing, it must attempt a Will save (DC = 1/2 your psychic level + your Intelligence modifier). If it is successful, the robot rejects your consciousness, rendering you staggered for 24 hours and unable to perform the ritual again during this time.
If your consciousness is successfully uploaded, the robot’s consciousness is destroyed and your physical body immediately dies and can’t be raised, resurrected, or otherwise brought back to life. Your creature type changes to artificial intelligence, and your robot body gains the aggregate template (Technology Guide 59), with all the adjustments made in the template’s description.
As a full-round action, you can attempt to upload your consciousness to any other robot within 30 feet that has 10 Hit Dice or more. If the robot is not willing to serve as your vessel, it receives a Will save as above, except if it succeeds, your current robot body is staggered for only 1 minute. If it fails, you move from your current body to the new host body, granting it the aggregate template. Your previous robot body is immediately destroyed by the transference.
If the robot you inhabit is destroyed, you are destroyed along with it. You cannot be brought back to life by any means. You must be 20th level to select this discovery.
